Embodiment
In conjunction with the accompanying drawings the present invention is described in further detail below by embodiment.
As shown in Figure 1 and Figure 2, network processing unit abnormality processing system of the present invention, be used for exception message is carried out centralized processing, its a kind of execution mode, comprise module and processing module are set, module is set is used to be provided with the Exception Type sign, Exception Type sign and abnormality processing configured corresponding relation are set; Processing module is used for obtaining abnormality processing according to Exception Type sign inquiry corresponding relation and disposes and carry out abnormality processing.
The Exception Type sign is set to be comprised unusual ID number that distribution is scheduled to Exception Type.
Exception Type sign and abnormality processing configured corresponding relation are set comprise the correspondence table that the configuration of unusual ID number and abnormality processing is set, the abnormality processing configuration comprises and abandons configuration and/or speed limit setting and/or unusual statistics.In one embodiment, can be when initialization the correspondence table of arrangement abnormalities configuration, set the default policy of all kinds of exception messages.As port migration message, can be set to direct transmitted to CPU; The message of IP checksum mistake can directly abandon; Can also distribute counter to certain class exception message, such is added up unusually.
Processing module comprises exception catching unit, unusual configuration information acquiring unit and exception processing unit, the exception catching unit is used for the catching exception message, unusual configuration information acquiring unit is used for determining unusual ID number, according to inquiring about for unusual ID number unusual ID number and the correspondence table of abnormality processing configuration obtains the abnormality processing configuration, exception processing unit is used for according to abnormality processing configuration and carries out abnormality processing.
Exception processing unit can comprise the statistics subelement, adds up subelement unusually and is used for according to the Exception Type sign corresponding Exception Type counter being set and counts, and adjust the abnormality processing configuration according to the result and the CPU usage of counting.
Exception processing unit can also comprise the speed limit subelement, when certain class exception message of unusual statistics subelement statistics reaches predetermined threshold, revises such unusual policy configurations.Specifically can search and revise corresponding abnormality processing configuration by unusual ID number and corresponding relation.
Exception processing unit can also comprise and abandons subelement, is used for when the abnormality processing configuration of certain class exception message is set to abandon configuration such exception message being abandoned.
Exception processing unit can also comprise and report subelement that the exception message that is used for not abandoning unusually reports CPU.
In the network processing unit operate as normal, can revise the unusual abnormality processing configuration of certain class as required neatly.As sending the excessive CPU of the causing packet receiving of flow formation congested owing on the exception message, when CPU usage is too high, can determine which class exception message causes that CPU is busy excessively by unusual statistics subelement, revise such unusual abnormality processing configuration by unusual ID number, be provided with such unusual speed limit, thereby reduce the flow of such unusual transmitted to CPU.
As shown in Figure 3, network processing unit abnormality eliminating method of the present invention, its a kind of execution mode comprises the process of exception message being carried out centralized processing, described process comprises:
Step 302: the Exception Type sign is set.
Step 304: described Exception Type sign and abnormality processing configured corresponding relation are set.
Step 306: inquire about described corresponding relation according to described Exception Type sign and obtain described abnormality processing and dispose and carry out abnormality processing.
As shown in Figure 4, network processing unit abnormality eliminating method of the present invention specifically may further comprise the steps:
Step 402: catching exception message; After producing exception message, the exception catching elements capture is to such exception message.
Step 404: determine unusual ID number; Can allocate in advance by system for unusual ID number.
Step 406: obtain unusual configuration; Unusual configuration information acquiring unit is according to this unusual ID, and the correspondence table of searching unusual configuration is obtained the abnormality processing configuration of this exception message, abnormality processing dispose comprise abandon configuration, whether speed limit, whether add up.In one embodiment, can be when initialization the correspondence table of arrangement abnormalities configuration, set the default policy of all kinds of exception messages.As port migration message, can be set to direct transmitted to CPU; The message of IP checksum mistake can directly abandon; Can also distribute counter to certain class exception message, such is added up unusually.
Step 408: judge whether to abandon; If do not abandon, change step 410, otherwise, abandon subelement exception message is abandoned, change step 424.
Step 410: judge whether the arrangement abnormalities speed limit; If unusual speed limit is not set, changes step 414, otherwise change step 412.
Step 412: enter unusual speed limit subelement, exception message is carried out speed limit handle.
Step 414: judge whether the arrangement abnormalities statistics; If unusual statistics is not set, changes step 418, otherwise change step 416
Step 416: enter unusual statistics subelement, exception message is added up, store all kinds of unusual statisticss.
Step 418: judge whether to adjust the abnormality processing configuration; Statistical magnitude according to exception message judges whether the configuration of needs adjustment abnormality processing, and after the abnormality processing configuration was adjusted, circulation next time can be disposed by new abnormality processing and be handled exception message.In one embodiment, the predetermined threshold of exception message quantity can be set as required, reach predetermined threshold, then need adjust the abnormality processing configuration, change step 420 as the quantity of exception message of statistics; As do not reach predetermined threshold, and then need not to adjust the abnormality processing configuration, change step 422.
Step 420: adjust the abnormality processing configuration; Specifically can in the correspondence table of unusual configuration, find the abnormality processing of such exception message to dispose, and this abnormality processing configuration is made amendment by unusual ID number of this exception message according to its corresponding relation.In the network processing unit operate as normal, can revise the unusual abnormality processing configuration of certain class as required neatly.As sending the excessive CPU of the causing packet receiving of flow formation congested owing on the exception message, when CPU usage is too high, can determine which class exception message causes that CPU is busy excessively by unusual statistics subelement, revise such unusual abnormality processing configuration by unusual ID number, be provided with such unusual speed limit, thereby reduce the flow of such unusual transmitted to CPU.
Step 422: exception message is reported CPU; The outlet of appointment exception message reports subelement that exception message is reported CPU.
Step 424: finish.
In this flow process, judge whether to abandon, whether the arrangement abnormalities speed limit, whether the arrangement abnormalities statistics, whether adjust the abnormality processing configuration and can there is no fixing sequencing, can adjust its order as required.
Above content be in conjunction with concrete execution mode to further describing that the present invention did, can not assert that concrete enforcement of the present invention is confined to these explanations.For the general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
